Can I accumulate some wine for future consumption without building a cellar or buying a refrigerator?
Yes. The longstanding notion that wine must be kept at 55 degrees or consumed immediately is nonsense–and destructive nonsense at that, with elitist consequences. It deters many less-than-wealthy newcomers from experiencing the pleasures of collecting a stash of special wines (and the savings made possible by stocking up during sales). Although those buying fancy Bordeaux or vintage Port for long ageing really do need special storage conditions, those who drink their wines with food within a couple of years after purchase will do just fine keeping them in a closet or a corner of the basement. If you can keep the temperature in the low 70s and avoid serious temperature fluctuations, your red wines will develop very nicely over the course of a few years. They will develop a bit more quickly than if they were stored at 55 degrees, but this is no disadvantage for near-term drinking. And since 95% of white wines decline rather than develop over time, you should be drinking these up quickly
